Discovery was first launched in 1984. It carried the Hubble Space Telescope to space in 1990 and also conducted the second and third service missions to Hubble.

Since we don't have any shuttle or space station passes to hunt, let's look south for Orion the great hunter.

His three belt stars are usually noticed first. After the trio of equally bright belt stars is found, look for Rigel as a brilliant white stellar point at the lower right.

Betelgeuse marks Orion's shoulder and can be spotted at the upper left of his belt as a glowing red-orange star.

Betelgeuse is a semiregular variable star about 600 light-years away. The light that you see tonight left the star in 1411.

Betelgeuse is a red supergiant. It's so large that if it were placed where our sun is, it would take up the space all the way to Jupiter.

That's an unbelievable distance and difficult to comprehend. If we think about it in terms of everyday objects around the house, just consider the size difference between a marble (our sun) and a school bus (Betelgeuse) and you'll get the idea of just how massive Betelgeuse really is.

A few articles floating around the Internet are reporting that when Betelgeuse explodes, we will have two suns in our sky. That's simply not true.

Betelgeuse is so distant that when it does explode, it will only be about as bright as Venus. That may be considered bad news for some, but I'm pretty happy it is so far away and will not gobble up Earth when it does turn into a supernova.

Keep your eyes on Betelgeuse. If it has already gone supernova, maybe you'll be the first to see it.
